In plant metabolism glycerol phosphate must be produced for the synthesis of various phospholipids, sulfolipids, galactolipids, and triglycerides. The metabolic reaction in leaf tissue of higher plants for glycerol phosphate synthesis is catalyzed by a DHAP2 reductase which has been partially purified from spinach leaves and castor bean endosperm, and which catalyzes the reduction of DHAP at pH 7.0 using NADH as the reductant (6,17 No. 12290. 2Abbreviations: DHAP, dihydroxyacetone phosphate; ME, mercaptoethanol; PVPP, polyvinylpolypyrrolidone. metabolism must be highly controlled, as is expected of compounds and enzymes at metabolic branch points.A number of free living algae produce glycerol as a major product of photosynthesis rather than accumulate starch or sucrose. Zooxanthellae, symbiotic, unicellular algae in the polyps of reef building corals and other marine invertebrates, excrete to their host up to 40% of their photosynthate as glycerol (14, 15).The halotolerant alga, Dunaliella tertiolecta (5,20) and Chiamydomonas (1 1)
